In the accompanying drawings:

Fig. 1 is a perspective view illustrating the guard as applied to the handle; and

Fig. 2 is a top plan view of the guard.

The numeral 1 indicates. the handle of the floor polishing or other similar machine to which the plate 2 is secured by means of the screws 3. Screws 4 extend through the plate 2 to secure the switch thereto, which switch is mounted beneath the plate and The guard plate 2 is provided with a slot 5 therein, upon the opposite side of which are the flared portions 6, and the trigger 7, which is attached to and operates the switch, extends through the slot 5 as shown in The guard is designated generally by the numeral 8 being provided with the flanged sides 9 and is secured to the plate 2 at its lower end. The guard is curved substantially throughout its length to correspond approximately to the curvature of the trigger 7.
